UPDATE: DEQ Extending Public Comment Period on Draft Air Quality Permit for CertainTeed Oxford
Facility
RALEIGH – The N.C. Department of Environmental Quality’s Division of Air Quality (DAQ) is giving an
additional 3 weeks for public comment on a draft air quality permit for CertainTeed, LLC – Oxford Facility in
Granville County.
Comments will now be accepted until Aug. 18, 2023. Also, the Division is now accepting comments via
telephone, in addition to email and postal mail.
CertainTeed currently holds a Title V air quality permit to operate an asphalt roofing manufacturing plant in
Oxford. The company has applied for a separate Title V air quality permit that would allow it to construct and
operate a new fiberglass mat manufacturing facility beside the current plant.
The new CertainTeed facility would be considered a major source facility because potential uncontrolled air
emissions of volatile organic compounds (VOCs) are above 100 tons per year and potential emissions of total
hazardous air pollutants (HAPs) are above 25 tons per year.
These emissions will be controlled by two parallel regenerative thermal oxidizers. A dust collector would also
control fugitive dust in the finishing area. The facility is subject to the National Emission Standards for
Hazardous Air Pollutants (NESHAP) for Wet-Formed Fiberglass Mat Production and the NESHAP for
Stationary Reciprocating Internal Combustion Engines.
Air dispersion modeling reviewed by DAQ shows the facility’s emissions of formaldehyde are expected to
comply with applicable standards and will not cause an exceedance of the acceptable ambient levels.
The draft permit includes conditions that ensure ambient levels of all pollutants beyond the facility’s fence line
comply with emission standards, including applicable health-based standards. The facility would also be subject
to recordkeeping requirements and regular inspections.
Copies of the public notice, draft permit, draft permit review, draft environmental justice report, permit
application, and a one-page project fact sheet are available online.
Comments or requests for a public hearing will be accepted until Friday, Aug. 18, 2023, at 5 p.m. Comments can
be emailed to [e-mail] with “CertainTeed.22A” in the subject line, or left via voice
mail by calling 919-707-8726. Comments can also be mailed to:
NCDEQ Division of Air Quality
1641 Mail Service Center
Raleigh, North Carolina 27699-1641
The Division will consider all public comments before making a final decision on the proposed permit.
